Application filed February 29, 1904. Serial No. 195,981. (No model.)

T0 (0 'IJI/MTIII/ 1115 may con/(smut:

Be it known that .1, Dr] LAsKI T. Cnnuoxs, a citizen of the UnitedStates, residing at llorncllsville, in the county of filbQUlJGll andMate of New York, have invented a new and useful Belt-Splice, of which.the following is a specilication.

This invention relates to belt-splices.

The object of the invention is in a thoroughly feasible and practicalmanner to obviate the presentation of abutting edges extendinglongitudinally or transversely of the belt, thereby greatly tostrengthen the union between the belt ends and to cause theabradingsurface at the point of juncture of the said ends to cutsmoothly and without the formation of grooves in the work.

As is well-known, the ordinary procedure of securing together theabutting ends of a sandpapenbelt, such as is used in furniturefactories,is to bring the ends together and hold them juxtaposed by a flexiblebacking or reinforce pasted to the back of the belt and covering themeeting edges thereof. The abutting edges may be disposed at rightangles to the length of the belt or obliquely thereto; but in eitherevent there are presented straight edges which if loosened from theirbacking or reinforce under the operation of the belt will result in thedestruction of the joint and also the formation of grooves in the workwhich will tend to mar the same. Furthermore, where a rupture in thejuncture between the belt ends occurs the union will gradually bedestroyed, for the reason as the belt revolves around the driving wheelsor pulleys at each revolution there is a further disruption orseparation of belt from its backing.

The above objectionable features are in the present instance positivelyeliminated by providing the belt ends with the tongues, the perimetersof which are formed throughout on curved lines, the tongues on one endbeing the counterpart of those on the other, so that when interlocked aneat, finished, and strong ioin t will be provided. As all of the edgesof the tongues are on curved lines, it follows that when the belt endsare assembled there will be no straight abutting edges extendinglongitudinally or transversely of the belt, and thus the uneven dressingof lumber will be obviated, and a positive retention of the interlockedrelation of the tongues will be assured. The tongues are heldinterloclu-id and against separation under longitudinal strain throughthe medium of a flexible backing, preferably of textile fabric, which isglued or cemented to the back of the belt and bridges the point ofjuncture between the two ends. The arrangement of the presentbelt-splice is such that even under long continued use there will be notendency of the interlocked tongues to separate from the backing, andthus a thoroughly effective and du able abrzuling-belt is effected.

\Vith the above and other objects in view, as will appear as the natureof the invention better understood, the same consists, generally stated,in the novel forms of belt-splice hereinafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, and.in which like characters of reference indicate corresponding parts,there are. illustrated two forms of embodin'ient of the invention, eachcapable of carrying the same into practical operation, it beingunderstood that the invention is not to be limited to the precisearrangements shown.

lln the drawings, Figure 1 is a view in elcvation, partly in section, ofan al.)radingbelt, showing the splice disposed transversely of thelength of the belt. Fig. 2 is a view in elevation, exhibiting a portionof a belt in which the splice is disposed obliquely to the length of thebelt. Fig. a view in transverse section through the belt.

The belt (designated generally 1) is made preferably from sandpaper,although any obliquely thereto preferably at an angle of aboutforty-five degrees; but whatever their angle of disposition be withrelation to the length of the belt there will never be formed straightabutting edges that will tend to groove the work over which the beltpasses. The positive holding of the tongues against separation underlongitudinal strain is secured by constructing them on the lines of adouble ogee curvethat is to say, on the lines of a figure formed byuniting the upper ends of two ogee curves with their bulges disposed inopposite directions, the perimeters of the tongues being formedthroughout on curved lines, so that when a head of one tongue is p0-sitioned between the necks of two adjacent tongues there is to allintent and purposes a dovetailed joint formed, the holding properties ofwhich are well known, but without the presentation of straight abuttingedges that will be present in the ordinary dovetail joint.

In addition to the advantages enumerated in this form of belt-splice thetongues by reason of the manner in which they are interlocked willgreatly increase the strength of the j uncture between the belt ends andwill cooperate with the backing in preventing their separation in use.

Having thus fully described my invention, what I claim is 1. Anabrading-belt having its ends united by interlocked tongues, theperimeters of which are formed throughout on curved lines.

2. An abrading-belt having it ends united by interlocked tongues, theperimeters of which are formed throughout on curved lines, and areinforce secured back of the tongues.

3. An abrading-belt having its ends united by interlocked approximatelydouble ogeeshaped tongues.

4. An abrading-belt having its ends united by interlocked approximatelydouble ogeeshaped tongues, and a reinforce secured back of the tongues.

5. An abrading-belt having its ends united by interlocked approximatelydouble ogeeshaped tongues, the heads of which are disposed in thedirection of the length of the belt.

6. An abrading-belt having its ends united by interlocked approximatelydouble ogeeshaped tongues, the heads of which are disposed in thedirection of the length of the belt, and a reinforce secured to the backof the belt and bridging the splice formed by the tongues.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
